Mousam is a free, open-source weather app for Linux desktops. It combines current conditions, hourly and multi-day forecasts, air-quality information, weather graphs, and sun and moon views in one interface. It uses Open-Meteo for weather data and can be installed through Flatpak, Snap, Debian-family packages where available, or from source.
What is Mousam?
Mousam is desktop software, not a weather device or subscription service. Its project describes it as “Weather at a Glance,” and the app is designed to show several kinds of local weather information together. You can add multiple locations and choose metric or imperial units.
The project’s feature list includes current temperature, humidity, wind speed, UV index, pressure, air quality, and precipitation and wind tracking. Its interface also offers compact mode, dynamic backgrounds, and notifications. The exact set of information displayed can depend on the selected location and available data.
What forecasts and weather views does it show?
Hourly and multi-day forecasts
Mousam provides hourly forecast information, along with presentations for tomorrow and a seven-day outlook. Users can switch between tomorrow’s forecast and the seven-day view. These are forecast displays; the listed views do not by themselves establish forecast accuracy for a particular location.

Graphs and sky information
The app includes hourly temperature, wind, and precipitation tracking, plus graphs for sun and moon positions. These views are useful for seeing how conditions or sky position change over time rather than relying only on a current-temperature reading.
Air quality
Mousam includes air-quality information, and Debian’s application metadata describes pollutant tracking. The project sources do not specify a pollutant list or establish that every pollutant is available for every location.

What weather data does Mousam use?
Mousam names Open-Meteo as its weather-data provider. The project README credits Open-Meteo for providing weather data free of cost. This identifies the source used by Mousam; it does not mean that the app guarantees uninterrupted availability or a particular level of forecast accuracy.

Available routes documented by the project and distribution listings include Flatpak, Snap, Debian-family packaging where available, and building from source with Meson. The commands and package availability can differ by distribution, so use the project’s current instructions for the method you choose.

Yes. Mousam is distributed under the GNU General Public License, version 3 or later (GPL-3.0-or-later). Flathub and Debian metadata also identify the application as community-developed and GPL-licensed. That license and the project’s free-of-cost data credit make Mousam a no-subscription option in the sources listed here.
